1986 Atlantic hurricane season

The 1986 Atlantic hurricane season was a very inactive season that produced 10 depressions, 6 named storms, 4 hurricanes, and no major hurricanes. The season officially began on June 1, 1986, and lasted until November 30, 1986. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. During the 1986 season, the first subtropical depression formed in the first week of June, while the last tropical cyclone dissipated at the end of the third week of November. The 1986 season had lower than average activity because of an ongoing El Niño event, and was the least active season in the North Atlantic since the 1983 Atlantic hurricane season. This was also the first season since 1972 to have no major hurricanes.[1]

The season started on June 5 when Subtropical Depression One formed near the Bahamas, which would later gain tropical characteristics and become the first tropical storm of the season; Tropical Storm Andrew. On June 9, Andrew would later be absorbed by a larger low pressure system. On June 23, the season's first hurricane formed; Bonnie, although it attained hurricane status on June 25, just two days after Bonnie's formation. Two more tropical depressions followed suit later in the season. On August 13, the season's fifth tropical depression formed and would later become Hurricane Charley four days later. After Charley dissipated, two more tropical depressions formed on August 31 and September 1. Both dissipated on September 4. On September 7, Tropical Storm Danielle formed and would dissipate on September 10. Just after Danielle dissipated, Hurricane Earl formed and would later become the strongest system of the 1986 Atlantic hurricane season, peaking as a 105 mph Category 2 hurricane and 979 mbars in lowest pressure. No tropical cyclones formed during the months of October and the first half of November. That is, until Hurricane Frances became the latest sixth named storm on record since tropical cyclones were first named in 1950. The season came to a close on November 21, which was when Frances dissipated.

Seasonal forecast edit

Dr. William M. Gray of Colorado State University issued forecasts on May 29 and July 28 indicating within both forecasts the anticipation of a below normal hurricane season. In May, a total of 8 named tropical storms were expected, with four hurricanes expected, 15 days with hurricanes, and a total of 35 days with a tropical storm active in the northern Atlantic Ocean. In July, the numbers were dropped to a total of 7 named storms, 4 hurricanes, 10 hurricane days, and 25 days with a named tropical storm, which almost perfectly verified.[2]

The season's activity was reflected with a cumulative accumulated cyclone energy (ACE) rating of 36,[11] which is classified as "below normal".[12] ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time, as well as particularly strong hurricanes, have high ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical cyclones are excluded from the total.[13]

Systems edit

Tropical Storm Andrew edit

Tropical storm (SSHWS)
DurationJune 5 – June 8
Peak intensity50 mph (85 km/h) (1-min);
999 mbar (hPa)

In early June, a large area of disturbed weather persisted over the Greater Antilles, bringing heavy rains to the islands. The area moved northward, developing a circulation over the Bahamas. Strong upper-level winds caused when satellite imagery showed a circulation developing over the Bahamas. Strong upper-level winds caused the structure to resemble a subtropical cyclone, and as a result, the system was classified as a subtropical depression on June 5.[4][14] The depression moved to the northwest and transitioned into a tropical storm on June 6; it was named Andrew about 258 mi (415 km) southeast of Charleston, South Carolina.[14] The tropical storm approached the South Carolina coast within 115 mi (185 km) before recurving to the northeast on June 7. The storm passed within 70 mi (110 km) of Cape Hatteras while recurving, while near its peak intensity of 50 mph (80 km/h). The storm accelerated to the northeast, briefly crossing into the forecasting territory of Environment Canada, the first of three storms of the season to do so,[15] before ultimately being absorbed by a low pressure system over Canada on June 8.[14]

While active, Andrew posed a threat to the Carolinas. Gale warnings were posted from an area ranging from Cape Lookout to south of Virginia Beach, Virginia on June 7.[16] Waves reached heights of 12-foot (3.7 m) off the coast of the Carolinas,[17] which killed a person on Ocracoke Island. Three companions were also swept out, all of whom made it back to shore. At Wrightsville Beach and Carolina Beach, at least 40 swimmers were caught in the currents, four of whom were hospitalized.[18] The precursor to the storm produced heavy rainfall across Jamaica that caused a deadly flood event.[14]

Hurricane Bonnie edit

Category 1 hurricane (SSHWS)
DurationJune 23 – June 28
Peak intensity85 mph (140 km/h) (1-min);
990 mbar (hPa)

During late June, a frontal trough drifted into the northeastern Gulf of Mexico, and by June 22 a surface circulation formed. Tracking west-northwestward, it developed into Tropical Depression Two on June 23 while located about 330 miles (535 km) south of Pensacola, Florida. The next day, it attained tropical storm status, and with continued favorable conditions attained hurricane status on June 25 to the south of Louisiana. Bonnie turned to the northwest and made landfall near Sea Rim State Park in Texas. The storm quickly weakened over land as it turned to the north and northeast, and on June 28 it was absorbed by an approaching frontal zone in southeastern Missouri.[19]

Prior to moving ashore, 22,000 people were evacuated. Upon making landfall, Hurricane Bonnie produced a storm surge peaking at 5.2 feet (1.5 m) at Sabine Pass. Rainfall from the storm peaked at 13 inches (330 mm) in Ace, Texas,[20] which caused some street flooding and destroyed a small dam in Liberty County, Texas. The hurricane also spawned eleven tornadoes, which, in combination with moderate winds, destroyed about 25 residencies in southwestern Louisiana. Three storm deaths occurred in the Port Arthur, Texas area; two deaths occurred from separate car accidents, and another occurred after a partially paralyzed woman died in a house fire. Hurricane Bonnie caused minor damage totaling $2 million (1986 USD, $3.5 million 2006 USD).[21]

Tropical Depression Three edit

Tropical depression (SSHWS)
DurationJuly 23 – July 28
Peak intensity35 mph (55 km/h) (1-min);
1012 mbar (hPa)

The third tropical depression of the season was detected early on July 27 in the open waters of the Atlantic, north of Bermuda. While about 180 miles (290 km) north of the island, the storm was moving northward at 15 mph (24 km/h) while its maximum sustained winds were about 30 mph (48 km/h).[22] Later that afternoon, aircraft reconnaissance found no well-defined circulation and the storm's status was reduced from a depression. The depression never threatened any land areas.[23]

Unnumbered tropical depression edit

Tropical depression (SSHWS)
DurationAugust 4 – August 5
Peak intensity35 mph (55 km/h) (1-min);
1012 mbar (hPa)

A tropical disturbance was detected on August 4 in the northwestern Gulf of Mexico along the lower Texas coast. The low-pressure system moved slowly toward land, limiting the system's development.[24] On August 5, the system became organized enough to be considered a tropical depression.[25] The storm moved inland overnight, dumping several inches of rain over South Texas and causing street flooding in Brownsville and nearby South Padre Island. The system caused rainfall up to 4.45 inches (113 mm) in some areas but had no major problems attributed to it.[25][26] This storm was not carried as a depression operationally, and thus has no assigned number.[1]

Hurricane Charley edit

Category 1 hurricane (SSHWS)
DurationAugust 13 – August 20
Peak intensity80 mph (130 km/h) (1-min);
987 mbar (hPa)

Hurricane Charley was the first hurricane to threaten the east-central United States since Hurricane Gloria in the previous year. The third tropical storm and second hurricane of the season, Charley formed as a subtropical low on August 13 along the Florida panhandle. A few days later intensified it into a tropical storm off the coast of South Carolina, and Charley attained hurricane status before moving across eastern North Carolina. It gradually weakened over the north Atlantic Ocean before transitioning into an extratropical cyclone, though its remnants remained identifiable for over a week until after crossing the British Isles and dissipating on August 30.[27]

The storm brought light to moderate precipitation along its path through the southeastern United States. In Georgia and South Carolina, the rainfall alleviated drought conditions.[28] In North Carolina, where the hurricane made landfall, tidal flooding and downed trees were the primary impact. The storm brought high winds to southeastern Virginia, where 110,000 people were left without power. Minor damage extended along the Atlantic coastline northward through Massachusetts. One traffic fatality was reported each in North Carolina and Virginia. Three people in Maryland died due to a plane crash related to the storm. Throughout the United States, Hurricane Charley caused an estimated $15 million in damage (1986 US$, $29 million 2008 USD).[27]

As an extratropical cyclone, Charley brought heavy rainfall and strong winds to Ireland and the United Kingdom, causing at least 11 deaths.[29] In Ireland, the rainfall set records for 24‑hour totals, including an accumulation of more than 7.8 in (200 mm) which set the record for the greatest daily rainfall total in the country. In the country, the rainfall caused widespread flooding, resulting in two rivers overflowing their banks. In the Dublin area, 451 buildings were flooded, some up to a depth of 8 ft (2.4 m).[30] In the United Kingdom, the storm caused downed trees and power lines, as well as flooded rivers.[29]

Tropical Depression Five edit

Tropical depression (SSHWS)
DurationAugust 30 – September 4
Peak intensity35 mph (55 km/h) (1-min);
1016 mbar (hPa)

This tropical depression formed in the eastern tropical Atlantic Ocean on August 31. The depression moved west-northwest, then northwest away from the Caribbean Sea without further development before dissipating east-southeast of Bermuda on September 4.[1]

Tropical Depression Six edit

Tropical depression (SSHWS)
DurationSeptember 1 – September 4
Peak intensity35 mph (55 km/h) (1-min);
1003 mbar (hPa)

A tropical wave crossed the Caribbean sea, moving into a favorable upper environment in the western Caribbean sea on August 31. The system formed into a weak tropical depression before crossing the Yucatán peninsula, becoming better organized as it moved into the south-central and western Gulf of Mexico between September 1 and 3. The system moved ashore east-central Mexico before quickly dissipating as a tropical cyclone on September 4. Satellite imagery revealed that its residual cloud pattern persisted over Mexico for an additional couple of days before degenerating. Heavy rainfall fell primarily north of its track, with the maximum across northeast Mexico falling at El Barranco/Altamira, where a total of 9.33 inches (237 mm) was measured.[31]

Tropical Storm Danielle edit

Tropical storm (SSHWS)
DurationSeptember 7 – September 10
Peak intensity60 mph (95 km/h) (1-min);
1000 mbar (hPa)

On September 1, a tropical wave moved off the coast of Africa and headed westward. The disturbance was below the 10 degree latitude as it organized into a tropical depression on September 7 and then a tropical storm later that day. Danielle peaked as a 60 mph (97 km/h) storm on September 8, while Reconnaissance Aircraft reported gusts of up to hurricane force. After passing through the Lesser Antilles, Danielle encountered vertical wind shear, and on September 10 it dissipated in the central Caribbean. The remnants continued westward and ultimately regenerated into Tropical Storm Lester.[32]

The islands of Saint Vincent and the Grenadines experienced wind gusts up to hurricane force, causing severe power outages and causing roof damage. In the Grenadines, the storm drove a coast guard ship aground,[33] while five people were injured and hundreds of homes were destroyed. Torrential rainfall produced several mudslides, which, in turn, damaged roads, bridges, electricity, and water services.[34] Danielle also destroyed twelve homes on the island of Barbados.[35] In Trinidad and Tobago, strong flooding of up to four feet caused 27 landslides, destroying four bridges. The storm caused $8 million in damage in Tobago.[36] Total damage from the storm amounted to $9.2 million (1986 USD), mostly to crops, though no deaths were reported.[34]

Hurricane Earl edit

Category 2 hurricane (SSHWS)
DurationSeptember 10 – September 18
Peak intensity105 mph (165 km/h) (1-min);
979 mbar (hPa)

The strongest storm of the season began as a tropical wave off Africa on September 4. After moving across the tropical Atlantic Ocean it developed into Tropical Depression Eight on September 10 while about 1240 miles (2000 km) east of Puerto Rico. The depression quickly strengthened and reached hurricane strength on September 11, peaked as a Category 2 hurricane on September 12 as it made a half circle, weakened to a Category 1 on September 16 and bounced back the way it came. Earl then turned north and became extratropical southeast of Newfoundland on September 19. At its peak, Earl had sustained winds of 105 mph (170 km/h) and a minimum central pressure of 979 mbar.[37]

Hurricane Frances edit

Category 1 hurricane (SSHWS)
DurationNovember 18 – November 21
Peak intensity85 mph (140 km/h) (1-min);
1000 mbar (hPa)

First spotted as a tropical disturbance near the Lesser Antilles on November 15, the system moved generally northward while slowly developing. The system organized into a tropical depression on November 18 and quickly strengthened into a tropical storm. The storm curved northeast and strengthened further, reaching hurricane strength on November 20. However, a surface high-pressure system to the north caused the storm to weaken as the vertical wind shear increased over its center. Frances was later absorbed by an extratropical cyclone on November 21.[38]

Storm names edit

The following list of names was used for named storms that formed in the north Atlantic in 1986.[39] This is the same list used for the 1980 season except for Andrew,[40] which replaced Allen, and was used for the first time in 1986. No names were retired from this list following the season,[41] and it was used again for the 1992 season.[42]
